All data analysis was conducted in the Integrated Research Environment of the Federal Statistical Research Data Center (FSRDCs). The code provided here includes redacted variable names, dataset names, and dataset paths, since that information is protected by Title 13 and Title 26 of the U.S. Code. 

Researchers who would like to replicate or review this analysis within the FSRDCs should take the following steps:

•	Propose an FSRDC project that includes the following datasets: IRS Form 1040 (1969, 1974, 1979, 1984, 1989, 1994, 1999); Current Population Survey ASEC (1973, 1985, 1991, 1995, 2000); Current Population Survey PIK crosswalks (1973, 1985, 1991, 1995, 2000); Decennial Census (1940, 2000)

•	Request access to CES Technical Note 25-XX (“Replication Documentation for
“Newly Available Individual-level U.S. Tax Data from 1969-1994”) by contacting an FSRDC Administrator or CES.Technical.Notes.List@census.gov. The technical note contains the same code provided here, but with unredacted information on variable names, dataset names, and dataset paths.

This public code release contains seven SAS program files that will replicate all the data found in the paper, in their unrounded forms (data were additionally rounded prior release from the FSRDC environment).
The table below identifies the programs used to pull the data.
